Product Description
V Notch Knife Edge Gate Valves are useful in cutting tough material like Pulp, resins, slurry, etc. These are available in Pneumatic and Motorised versions. Body in Cast Iron, WCB, SS or SS Alloys.Versatile Seat and Body MaterialsChoose the right seat material-Metal, PTFE, EPDM, or NBR-to optimize valve performance based on media, process fluid characteristics, and temperature requirements. Body options in stainless steel, cast iron, carbon steel, or alloy steel offer durability and wide applicability in varied industrial sectors.
Advanced Valve Structure for Precise ControlThe V-notch gate paired with knife-edge design ensures precise flow regulation, especially for challenging media such as slurry and semi-solids. Its two-way operation, precision machining, and corrosion-resistant epoxy finish enhance longevity and reliability.
Customizable Mounting and Actuation OptionsInstall the valve in either horizontal or vertical positions to suit piping layouts. The valve can be operated manually (handwheel), pneumatically, or electrically, allowing integration into automated systems or manual processes as required.
FAQ's of V NOTCH KNIFE GATE VALVE:
Q: How is the seat material selected for a V Notch Knife Gate Valve?
A: The seat material-Metal, PTFE, EPDM, or NBR-is chosen depending on the process media, operating temperature, and chemical compatibility. For corrosive chemicals or high-temperature applications, PTFE and Metal seats are ideal, while EPDM and NBR work well for general water, slurry, or semi-solid flows.
Q: What are the benefits of a V-notch knife gate design versus a standard gate valve?
A: The V-notch knife gate provides enhanced precision in flow control, especially for throttling services with slurries or viscous media. It allows for linear flow adjustment, reducing clogging incidents and promoting smoother operation in difficult process conditions.
Q: When should a split body be preferred over a one-piece body type?
A: Split body construction is recommended for larger valve sizes, high maintenance environments, or when frequent internal inspection is needed. One-piece bodies offer compactness and robustness for standard applications where maintenance access is not a primary concern.
Q: Where can these valves be installed in industrial processes?
A: V Notch Knife Gate Valves are suited for installation in pipelines transporting slurry, liquids, or semi-solids. Key industries include pulp & paper, mining, water treatment, chemical processing, and power plants, at locations requiring reliable flow shutoff or regulation.
Q: What is the process for operating the valve with different actuators?
A: Depending on system requirements, operation can be manual (via handwheel), pneumatic (cylinder actuator), or electric (motorized actuator). Manual control is suited for low frequency use; pneumatic and electric actuators enable remote and automatic operation, integrating into control systems for process automation.
Q: How does customizable port size and connection type benefit users?
A: Custom port sizes (50mm to 1200mm) and connection options (flanged, wafer, lugged) allow seamless integration into existing pipeline dimensions and layouts. This adaptability ensures compatibility with a wide range of systems and simplifies installation and maintenance.
